Medium-voltage cable joint
First Claim
1. A joint kit for joining opposing ends of two medium-voltage cables, comprising;
- an electrically-conductive connector for connecting the conductors of the cables;
an electrically-insulating surround material for enveloping the connector;
a partial discharge detector, comprising an electrically-conductive member formable into a generally cylindrical conductive sheath around the insulating surround, from which an electrically-conductive element extends in an axial direction along the length of at least one of the cables;
an outer protective tube for surrounding the remainder of the kit, wherein the conductive element is sufficiently long to project out of the protective tube.

Abstract
A kit for joining opposing ends of two medium-voltage (between about 3.3 kV and about 52 kV) electrical power distribution cables, comprising an electrically-conductive connector for connecting the conductors of the cables, an electrically-insulating surround material for enveloping the connector, a partial discharge detector, comprising a generally cylindrical, electrically-conductive sheath around the insulating surround, from which an electrically-conductive element extends in an axial direction along the length of at least one of the cables, an outer protective tube for surrounding the remainder of the kit, wherein the conductive element is sufficiently long to project out of the protective tube. A partial discharge detector and a medium voltage cable run are also described.
